Funny:
I just finished rebuilding a PAS-3 with stock circuit,
1. had to revamp heater supplies,as is typical, as the unit used a voltage doubler circuit and you need 15.2 volts to get heaters of the 12 AX&'s up to snuff. Inital heater reading read only 19 volts. with UF diodes got the filament up to 24 volts.
2, changed coupling caps, using a 1.5 UF unit polypropylene.
3. Used diode separation to separate each B+ stage of the tubes in lone stage Owner was not going to use Phono so I left the phono section alone.
result was a remarkably airy and open soundstage with good control over the frequency extremes. enough so I am in the process of doing the same to a couple of PAs units I had and was going to use for parts.
